I'm looking to test out a couple kinds of strings on one of my basses. I want to put a set on, test them out, take them off, and put a new set on. (I'd like to test flats versus rounds, steels versus nickel, etc...) Once I decide which ones I like best will I be able to put them back on and get regular playing life out of them, or does putting them on and then pulling them off somehow mess them up? Just a thought that occured. Thanks.
